Rotatable dual spacing clamp tie

Abstract

A dual spacing clamp tie includes a rotatable locking head and two flexible straps extending outwardly in opposite directions from the locking head. The straps are insertable through the locking head to form two, spaced loops that can be used to secure items in spaced, parallel relationship to each other. A pair of releasable pawls in the locking head secures the straps around the items to be secured. An aperture may be provided through the locking head or adjacent the locking head for securing the dual spacing clamp tie to a mounting structure such as a threaded stud. An additional pawl mechanism may be provided within the aperture to secure the clamp tie to the mounting stud. Alternatively, a nut or other fastener may be used to secure the clamp tie to the mounting stud.

       6. The rotatable dual spacing clamp tie of  claim 3  wherein said mounting boss includes a central axis and wherein said pawl mechanism is orientated obliquely relative to the central axis of said mounting boss. 
     
     
       7. The rotatable dual spacing clamp tie of  claim 6  wherein said pawl mechanism includes a distal end point located within the aperture and wherein said pawl mechanism includes an innermost portion proximate to the wall surface defining said aperture. 
     
     
       8. The rotatable dual spacing clamp tie of  claim 6  wherein said pawl mechanism includes a plurality of barbs located within the aperture. 
     
     
       9. The rotatable dual spacing clamp tie of  claim 1  wherein said head members are supported by and rotatable relative to an independently formed disc member. 
     
     
       10. The rotatable dual spacing clamp tie of  claim 9  wherein said disc member includes a centrally located pivot pin and a primary, radially extending, flange portion, and wherein said locking head members each include means for pivotally receiving and attaching said head members to said pivot pin of said disc member. 
     
     
       11. The rotatable dual spacing clamp tie of  claim 10  wherein said means for pivotally receiving and attaching said head members to said pivot pin includes a secondary flange portion radially extending from a distal end of said pivot pin and wherein said locking head members each include a centrally located re-entrant bore having an interior configuration adapted to receive and rotatably engage said secondary flange portion. 
     
     
       12. The rotatable dual spacing clamp tie of  claim 1 , wherein one of said bifurcated head members contains an integrally formed pivot member extending laterally therefrom and including a radially extending integral flange proximate to its distal end, and wherein the other of said bifurcated locking members includes a re-entrant bore for substantially conforming to the configuration of said integrally formed pivot member. 
     
     
       13. The rotatable dual spacing clamp tie of  claim 1 , wherein one of said bifurcated head members contains an integrally formed pivot member extending laterally therefrom and including a radially extending integral flange proximate to its distal end, and wherein the other of said bifurcated locking members includes a U-shaped channel for receiving said integrally formed pivot member. 
     
     
       14. The rotatable dual spacing clamp tie of  claim 13 , wherein the other of said bifurcated locking members further includes a retaining means for retaining said pivot member. 
     
     
       15. The rotatable dual spacing tie clamp of  claim 14 , wherein said retaining means comprises a cantilevered snap having a head portion, said head portion engaging said pivot member flange. 
     
     
       16. The rotatable dual spacing clamp tie of  claim 1 , wherein the first of said bifurcated head members includes an integrally formed pivot pin member extending laterally therefrom and a retaining means proximate to the first head member distal end, and wherein the second of said bifurcated head members includes an integrally formed pivot pin member extending laterally therefrom and a retaining means proximate to the second head member distal end. 
     
     
       17. The rotatable dual spacing clamp tie of  claim 16 , wherein at least one of said retaining means comprises a C-shaped clamp.
